EnterpriseDB acquires Altinity to bring PostgreSQL and ClickHouse capabilities under one company, giving its EDB Postgres AI platform a broader base for managing transactional and real-time analytical data. The companies did not disclose financial terms.

Altinity’s engineers are now part of EnterpriseDB. The company said the move will let it support and contribute to both the PostgreSQL and ClickHouse projects while developing its Postgres AI platform.

EnterpriseDB Acquires Altinity as It Expands Its Platform

EnterpriseDB’s platform is built on PostgreSQL, while Altinity provides a platform built on ClickHouse. The acquisition combines teams working on the two open-source database engines, which the source describes as widely used.

Near-term development plans include a shared Apache Iceberg catalog and consistent access controls across the companies’ currently separate PostgreSQL and ClickHouse environments. Those pieces are not yet in place, leaving integration as work ahead for the combined team.

Before the deal, EnterpriseDB customers had to turn to other providers for analytical data workloads, according to Devin Pratt, an analyst at IDC. He said enterprise buyers want to simplify data management by reducing the number of products and vendors they use.

Pratt described the acquisition as a way for EnterpriseDB to cover operational and analytical needs from one vendor. He also said the company’s focus on data sovereignty and deployments across on-premises, multi-cloud and hybrid environments helps distinguish it from competitors.

EnterpriseDB had already added ClickHouse support to its multi-model database platform earlier this year. The acquisition builds on that initial support. Nancy Hensley, EnterpriseDB’s chief product officer, said customers including large enterprises and government entities want data available in real time for agents and human users.

She said data spread across separate systems has hindered work on agents and other AI tools. Bringing PostgreSQL and ClickHouse capabilities together, she said, can provide a unified multi-model architecture for data and AI initiatives.

Matt Aslett, an analyst at ISG, said the acquisition also comes as ClickHouse Inc. competes with EnterpriseDB. ClickHouse Inc., the leading contributor to the ClickHouse open-source project, launched managed PostgreSQL capabilities this year. Aslett described Altinity as a direct competitor to ClickHouse Inc.’s software, services and support portfolio.

Integration Remains the Test

EnterpriseDB aims to make EDB Postgres AI a unified, sovereign platform for agentic AI, according to the company. Pratt called the deal a meaningful step toward that goal, but said it does not complete the transition.

EnterpriseDB still needs to integrate Altinity’s enterprise ClickHouse capabilities, which are expected before the start of 2027. The company also plans the shared Apache Iceberg catalog and access controls across PostgreSQL and ClickHouse. Until that work is complete, the environments remain separate.

Aslett said considerable engineering work remains before EnterpriseDB can deliver on its platform plans. For now, the acquisition expands the company’s ability to support operational and analytical data processing across two separate environments. The integration work and the planned catalog and controls will determine how closely those capabilities operate together.

For customers, the immediate change is that Altinity’s engineers and ClickHouse capabilities are now part of EnterpriseDB. The next stated step is integration, including the catalog and access-control work, rather than a completed unified system.

EnterpriseDB’s announced plans therefore remain a work in progress: the acquisition brings the teams together, while shared tooling and controls are still to be developed.
